2003 FSVT Datalogging
I too have been having issues. XCAL3 - Running 64Bit Windows 7 via USB I also have Analog 1 hooked up to A/F wideband. Not really sure what is going on the length of the log capture varies from 30 seconds to 800 seconds. It seems like the communication stutters for a few seconds before it stops. Then the device disconnects itself from the SCP link to the computer.
Just wanted to let you know and find out if there is a solution.
